v docs pishe:
ftp.redhat.com ran vsftpd for the RedHat 7.2 release. vsftpd achieved 4,000
concurrent users on a single machine with 1Gb RAM. Even with this insane user
count, bandwidth remained totally saturated. The user count could have been
higher, but the machine ran out of processes.

vsftpd is now a proven stable solution. Of particular note, RedHat used vsftpd
to enable ftp.redhat.com to support 15,000 concurrent users across their
server pool. This extreme load was generated by the release of RedHat 7.2 to
the world.

Qwno za tezi 15 000 ide re4 i za qki machini vyrzani v load balancing pool;-)
